We have been reporting on Hulu’s trial of a new paid subscription called Hulu Plus. Hulu Plus differs from the free version of Hulu in that paid subscribers will have access to all the episodes from a television show’s season rather than only a handful offered with the free version. Hulu Plus had only been available by invitation, but that has now changed.

The service has now been made available without an invitation. Hulu says the reason for this is so the company can continue to scale its infrastructure to a larger customer base. In addition to opening Hulu Plus for more subscribers, Hulu also announced the expansion of the number of devices supported by the service. Hulu Plus is now available on Sony BRAVIA 2010 televisions with more BRAVIA devices slated to support the service in the future. Also, PS3 owners with a PlayStation Network account will now be able to download and subscribe to Hulu Plus.
